Its not just the rod to consider, the reel also, they need to balance, get that right and it makes life easy, generally the lighter the better, within reason, depending on the average size of your target fish. I,ve caught plenty of fish using the rolling method, and now use the same, or similar technique hunting salmon, the rod/reel balance is critical, took me several trials and a good deal of expense finding the right reel to correctly balance the rod, but the difference is "feel", get it right and bites are more sensed than seen on the rodtop, plus you can hold the rod allday without tiring!
